Compliance overview
Scope and applicability
This standard is applicable to all types of institutions engaged in the assembly and fitting of prostheses. It covers the entire service process, including reception, examination, prescription, agreement signing, preparation, manufacturing, training, delivery, and follow-up. It is mandatory for all prosthetic fitting service providers operating in the Chinese market. The standard does not apply to the manufacturing of prosthetic components themselves, which are covered by separate component standards like GB 14722 and GB/T 13461.
Technical requirements
The standard specifies comprehensive service requirements for prosthetic fitting, with Chapter 6 being mandatory. It mandates a first-visit responsibility system, requiring clear division of labor and signature-based accountability throughout the process. Institutions must establish an internal quality management system and ensure their personnel, facilities, and environments meet specific operational standards. Key requirements include detailed patient reception and medical record-keeping, with records and fitting agreements required to be preserved for at least 15 years. The fitting process must follow strict procedures for measurement, modeling, and alignment. A formal prosthetic prescription must be issued, detailing the prosthesis type, components, and materials, and must be signed by the patient or their family. The standard outlines rigorous quality inspection protocols, requiring both initial and final adaptability evaluations. Initial checks assess correct wearing, socket fit, and alignment, while final checks verify compliance with the prescription, safety, and appearance. Upon delivery, institutions must provide a certificate of conformity, warranty card, and instruction manual. Institutions must respond to patient inquiries within 48 hours and conduct regular follow-ups, typically at 3-month, 6-month, or 1-year intervals.
Testing methods
The standard outlines specific evaluation procedures rather than traditional laboratory tests. Key assessments include the initial adaptability evaluation (checking socket fit, alignment, joint range of motion, and suspension) and the final adaptability evaluation (verifying prescription compliance, safety, and cosmetic appearance). For lower limb prostheses, dynamic walking and sitting checks are mandatory. Dimensional measurements must be conducted according to the referenced component standards, utilizing the detailed measurement forms provided in the normative appendices.
